Rotary 17979 NLGI 00 Grease 28.1 oz Bottle
The Rotary 17979 NLGI 00 Grade Grease is a semi-fluid lithium hydroxy stearate grease engineered for high-performance lubrication in demanding outdoor power equipment and landscape machinery applications. Supplied in a convenient 28.1 oz bottle.
What Is NLGI 00 Grease?
NLGI (National Lubricating Grease Institute) grades classify grease consistency from 000 (most fluid) to 6 (very firm). Grade 00 is a semi-fluid grease — thicker than oil but pourable — making it ideal for enclosed gear housings, differentials, and gearboxes where a fluid grease is required to flow through tight clearances and coat all moving surfaces.
Key Performance Properties
- Wear Protection: Additive package provides a protective film on metal surfaces to reduce friction and extend component life
- Corrosion Resistance: Inhibitors protect metal parts from rust and oxidation, especially in wet or outdoor environments
- Oxidation Stability: Resists breakdown over time, maintaining lubrication performance through extended service intervals
- Lithium Soap Thickener: Offers good water resistance and mechanical stability across a wide temperature range
Common Applications
- Lawn Mower Gearboxes: Deck spindle gearboxes and blade drive housings on walk-behind and riding mowers
- Rotary Cutter Gearboxes: Tail wheel and main gearboxes on rotary cutters and brush hogs
- Tiller Gear Cases: Front-tine and rear-tine tiller transmissions requiring semi-fluid lubrication
- Auger Drive Housings: Post hole digger and ice auger gear cases
- Enclosed Differentials: Walk-behind mower and small tractor differentials
- General Landscape Equipment: Any enclosed gear housing specifying NLGI 00 or semi-fluid grease

Always consult your equipment operator's manual to confirm the correct grease specification before servicing. Many OEM gearbox manufacturers specify NLGI 00 semi-fluid grease for enclosed gear cases.
